We have released LibreSSL 2.4.3, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon. It includes the following
changes:
* Reverted change that cleans up the EVP cipher context in
EVP_EncryptFinal() and EVP_DecryptFinal(). Some software relies on the
previous behaviour.
* Avoid unbounded memory growth in libssl, which can be triggered by a
TLS client repeatedly renegotiating and sending OCSP Status Request
TLS extensions.
* Avoid falling back to a weak digest for (EC)DH when using SNI with
libssl.
The LibreSSL project continues improvement of the codebase to reflect modern,
safe programming practices. We welcome feedback and improvements from the
broader community. Thanks to all of the contributors who helped make this
release possible.
